Speaking at gamescom 2012 in an open Q&A session, Cage commented: "Our actors all had to learn their lines and deliver them from memory. Ellen had hundreds of pages, worth about three or four movies.

"We shot for about 12 months, which is a very long period of time."

Cage also explained what appeals to him about producing cinematic video games.

He stated: "I love this medium, and I'm genuinely passionate about this new medium being born and that's growing every day. At the same time, I'm really not into having 30-minute cutscenes in a game and you're just showing films.

"If you played Heavy Rain, there are very few cutscenes and very few moments where you don't have control. I'm interested in [being able to] tell the story through interactivity and how you can be an actor in the experience."
